RVM script has to be run?

Ruby
1

Do I always have to run the RVM script to get Ruby loaded in it’s interpreter shell ?

I use rvm under bash in Ubuntu. When I start my shell, I just start using Ruby. I can call rvm if I need to, but it’s not necessary.

When I fire up bash on Linux Mint it says Ruby is not installed, it is installed with RVM.
So I run “source ~/.rvm/scripts/rvm” then “rvm --default use ruby” then I get the Ruby interpreter shell.
I tried to add a .ruby-version file in my home folder root, but that didn’t work either.
I did install Elasticsearch recently then exported JAVA_HOME in .profile, I wondering of that somehow affected Ruby. although I don’t see how it could have.
